Please specify the severity of this bug. Severity is defined here: https://bugzilla.redhat.com/page.cgi?id=fields.html#bug_severity. Hi Sachin, Goutham provided access information out of band, however the env is no longer accessible today. Please let us know if further triage in needed. (In reply to Sachin Punadikar from comment #19) > As per discussion with Goutham, with latest code, he was not able to > reproduce this issue. > Waiting for more details on this from him. Thank you Sachin! Apologies for the late response here. Yes, I'm unable to reproduce this issue with RHOSO 18 and RHCS 8. Originally, the issue was observed with RHCS 7 (container tag: 7-493), I'll try to reproduce this with RHCS 7. However, I'll close this bug and report a new one if the issue does occur with RHCS 7.

Description of problem: I'm using rhceph:7-493 (Reef) orchestrated by cephadm; and using OpenStack Manila to create an NFS export with CephFS. My setup includes a 3-node ceph nfs cluster, front-ended by the Ingress service ( with "haproxy-protocol" as ingress mode ). The setup has a Virtual IP using an IPv6 address, and the client/s specified in the export have IPv6 addresses as well. I'm unsure if this problem is in the ingress service (nothing relevant in the logging) or in NFS-Ganesha (I've added verbose/FULL_DEBUG logging to this report). OpenStack users have long used IPv6 with NFS-Ganesha, however, not with the latest version of NFS-Ganesha, and not when it is setup as a "ceph nfs" cluster service. Version-Release number of selected component (if applicable): - Ceph Version rhceph:7-493 - NFS-Ganesha package versions: nfs-utils-2.5.4-27.el9.x86_64 nfs-ganesha-selinux-5.7-5.el9cp.noarch nfs-ganesha-5.7-5.el9cp.x86_64 nfs-ganesha-rgw-5.7-5.el9cp.x86_64 nfs-ganesha-ceph-5.7-5.el9cp.x86_64 nfs-ganesha-rados-grace-5.7-5.el9cp.x86_64 nfs-ganesha-rados-urls-5.7-5.el9cp.x86_64 Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. Create a Manila share (CephFS subvolume) 2. Create a Manila access rule on the share with IPv6 client ("ceph nfs export apply") 3.
